2G Cell ID Layout
TIM has no advanced system for theyr GSM number layout, the cell id just increases by one on each sector. If there are two GSM cells per sector theyr id isnt related.
3G (UMTS/HSPA)
TIM uses 1-3 UMTS2000 cells and one UMTS900 cell. In 2016 TIM started launching lots of Basestations, those appear to have only one single UMTS cell with very little speed (about 1-5 Mbit down -51 dbm), but those Basestation seem to support future LTE upgrades.
Cell ID Layout
There is no Layout for UMTS frequencys. They get applayed one after another, it seems like TIM increases the count just by one with every new cell they launch.
4G (LTE)
TIM has 3 LTE blocks in use, 800 MHz (EDD B20) 10-15 MHz, 1800 MHz (DCS B3) 10-15-20 MHz, 2600 MHz (IMT-E B7) 15 MHz.
Cell ID Layout
If Celll ID starts with 7 or 8:
| Sector ID | Frequency Band |
| 21 | 2600 MHz (IMT-E) |
| 22 | 2600 MHz (IMT-E) |
| 23 | 2600 MHz (IMT-E) |
| 43 | 1800 MHz (DCS) |
| 42 | 1800 MHz (DCS) |
| 41 | 1800 MHz (DCS) |
| 61 | 1900 MHz (PCS) |
| 62 | 1900 MHz (PCS) |
| 63 | 1900 MHz (PCS) |
If Cell ID isn't starting with 7 or 8 sectors are named randomly.
